颈动脉体瘤诊断与治疗进展 总被引:4,自引:0,他引:4
颈动脉体瘤属于化学感受器肿瘤,具有家族遗传倾向。颈动脉体瘤的发生与SDH基因的突变有关。多数为良性,恶性率不超过10%,诊断恶性的标准为局部淋巴结或远处转移。应根据仔细的临床检查和特征性影像学结果做出诊断,影像学检查包括B超(多普勒)、CT、MRI/MRA及DSA。DSA检查可作为诊断颈动脉体瘤的金标准。一旦诊断颈动脉体瘤,应积极采取手术治疗。目前,放射治疗亦可作为治疗颈动脉体瘤的有效手段。本文对颈动脉体瘤的诊断及治疗进展作一简要综述。 相似文献

Glomus tumors known as paragangliomas are neoplasms arising from the neural crest. They are named according to the place they originate from. Tumors originating from the carotid body at the carotid bifurcation are called Carotid Body Tumors (CBT). Surgical intervention is planned according to the Shamblin classification. 17 patients were operated after being diagnosed with CBT in our clinic between February 2007 and June 2010. 12 (70.5%) of the patients were male, and 5 (29.4%) of the patients were female. The average age was 42 (ages ranging between 32 and 47). Nine of the patients were diagnosed and treated with Shamblin type I tumor, seven of the patients with type II and one patient with type III. Only one patient had bilateral carotid tumor. In all patients with Shamblin type I and II, blunt dissection of the tumor was conducted smoothly by means of thermal cautery in the subadventitial plane. The patient with Shamblin type III had tumor invasion in the carotid artery and adjacent tissues were in an adherent state. Therefore mass resection was carried out by resecting 2 cm of the distal portion of the common carotid artery and 3 cm of the proximal portion of the internal carotid artery. 6 mm of synthetic polytetrafluoroethylene graft was interpositioned between the common carotid artery and the internal carotid artery. External carotid artery was anastomosed to this graft in an end-to-end fashion. The patient developed vocal cord paralysis postoperatively on the lesion side. The patient who underwent bilateral tumor excision developed Baroreflex Failure Syndrome. In the two patients thrombus developed in the internal carotid artery in the early postoperative period. These patients underwent thrombectomy and developed hemiplegia on the lesion side. One of them died on the seventh post-operative day while in follow-up in the intensive care unit. Surgical resection is the recommended treatment for carotid body tumors. Shamblin I and II type tumors’ dimensions and pathological characteristics allow dissection. However Shamblin III tumors may require carotid artery resection and reconstruction due to tissue invasion. The possibility of post-operative cranial nerve paralysis and arterial thrombosis should be taken into account. 相似文献

ObjectivesCarotid body tumors (CBTs) are rare head and neck neoplasms, we aimed to propose a modification to the Shamblin's classification of CBTs.Materials and methodsThis retrospective study included 105 patients (116 CBTs) operated at our institution from March 2013 to July 2020. CBTs were divided by a modified Shamblin's classification into five subtypes (type I–V) based on the radiographic features. Correlations between modified classification and intraoperative bleeding, internal carotid artery (ICA) bypass and postoperative neural complications, as main outcomes, as well as other outcomes were analyzed.ResultsSurgeries for type V and type I CBTs had the most (median: 700 ml, IQR: 375–1575 ml) and least (median: 20 ml, IQR: 20–50 ml) bleeding, respectively. Intraoperatively, ICA bypass was needed in 41.7% (10/24) type V, 18.2% (8/44) type IV and 5.9% (1/17) type III lesions, but not in other subtypes (p = .001). Postoperatively, overall cranial nerve deficits (CND) were found most frequently in type V tumors (17/24, 70.8%) (p = .016). Permanent CND were found in 33.3% (8/24) type V and 4.5% (2/44) type IV lesions, but not in other subtypes (p = .001). Other outcomes including external carotid artery ligation, operation time, blood transfusion, postoperative intensive unit care and postoperative hospitalization also showed significant difference among different subtypes. Patients recovered uneventfully during a follow-up of 23.5 ± 16.2 months except for one ipsilateral recurrence at 42 months after surgery.ConclusionsThe modified classification was correlated with surgical outcomes of CBTs and will be helpful for making surgical plans. 相似文献

背景与目的:甲状腺癌绝大多数为分化较好的低度恶性癌,经规范治疗后,一般预后好,但仍有少数病例会复发。本研究旨在对其复发的原因、治疗及预后作一总结分析,以寻找复发原因和治疗措施。方法:对1980年1月至1996年1月间我科收治的44例甲状腺复发癌患者的临床和随访资料进行回顾性分析和总结。结果:44例复发甲状腺癌中,分化型甲状腺癌38例,其中乳头状癌28例、滤泡癌7例、髓样癌3例,未分化型即间变癌6例,分别占同期同种组织学类型甲状腺癌的4.1%(28/676)、18.9%(7/37)、8.1%(3/37)和42.9%(6/14)。33例为淋巴结复发(75%)。39例行复发癌灶局部广泛切除,术后辅以放疗;5例予单纯放疗。本组治疗后3年生存率分别为85.7%、71_4%、100%和0;5年生存率分别为60.7%、57.0%、66.7%和0;l0年生存率分别为35.7%、42.9%、33.3%和0。结论:初次手术时遗漏的临床和亚临床淋巴结转移灶是甲状腺癌术后复发的主要原因。甲状腺复发痛以手术治疗为主,治疗后其预后仍较好。 相似文献
